Dear all
I am trying to convert a fluent mesh to foam but I get the following error: FINISHED LEXING dimension of grid: 3 Creating shapes for 3-D cells Building patch-less mesh...Killed I've managed to convert the mesh of the same model but after increasing the number of elements (from 100,000 to 15 millions) I get this problem. Thanks in advance Luca |

Dear Bruno
The system has 8 GB of RAM and is 64bit. The utility that I used is fluentMeshToFoam best regards, Luca |

Hi Luca,
OK, then it's not a problem of using 32bit only. I forgot to also ask in the previous post:
For example (if my memory hasn't fail me), a simple test with blockMesh, for creating a simple cube shaped domain, using an hexahedral mesh with 8 million cells, it needed around 8GB of RAM. And this was just for the mesh... it didn't even have the fields! If the mesh were tetrahedral, perhaps it could go up to 16 million cells, but I'm not sure. Best regards, Bruno

The mesh was generated on the same machine and it counts 15 million of cells (full hexa). Then I guess I don't have enought RAM. I will try to d the conversion with the cluster that I will use for the simulations. Thanks a lot for the help
best regards, Luca |
